hello, my drone met some problem recently.i am using neo6m gps, and lpe shows strange behavior. lpe shows local position around (0,0) when pixhawk is powered, and when i hold drone and move 10 meters towards north, local position goes to (0,10), then it goes back to (0,0) slowly.i tried several times and no matter how i move, lpe can 'feel' the change of position and then goes back to (0,0), that make me confuse.i set lpe_fusion only use gps, baro.any suggestion will be help.
